This issue could be due to presence of static charges or internal hardware malfunction of the notebook. To isolate the exact cause of the issue, perform the steps provided below.

Step 1: Hard Reset

To perform a hard reset, please follow the steps listed below:

1. Unplug the AC adapter from the notebook PC and remove from any port replicator or docking station. 2. Remove the battery from the notebook battery compartment. 3. Press and hold down the power button for about 20 seconds. 4. Insert the battery and plug the AC adapter back into the notebook PC. 5. Press the power button to turn the notebook PC back on.

This will discharge the static charges from the notebook. Now turn on the notebook and check for the issue. If the issue persists, then remove and reseat the memory modules of the notebook and check for the issue.

Step 2: Remove and Reseat the Memory Modules

You can refer the service manual provided below for information to remove and reseat the memory modules of the notebook.

Refer page no: 53 & 54
NOTE: PDF manuals require the Adobe Acrobat Reader for viewing and printing.
If the issue persists after the above steps, then this could be due to internal hardware malfunction of the notebook and requires a detailed onsite diagnosis by a service technician. If your notebook is covered under HP Standard Warranty, then I would request you to contact HP Support to get your notebook repaired under warranty.

I believe the information provided would be helpful to isolate the issue with your notebook.

this occurs mostly due to static charges. perform the following:
1. Turn off the PC and disconnect the power supply.
2. Remove the battery from the notebook.
3. Press and hold the power button for 45 seconds.
This will discharge the static charges from the pc. Now check for the issue.

Due to regular use of the notebook, some static charges tend to stay in the computer, and sometimes results in not allowing the computer to function properly.

Please follow the power drain procedure to confirm the same:

1. Disconnect the AC Adapter. 2. Remove the Battery. 3. Hold the Power button down for 30seconds to 1 minute. 4. Put the Battery in. 5. Reconnect the AC adapter. 6. Turn on the Notebook power. 7. Restart the Notebook.

If the Notebook boots up you may fix the battery back. Try restarting the computer only with the AC power, without the battery & vice-versa. If the issue still persists then I request you to reset the memory modules, as sometimes the memory module connection get loose.

hi. I suspect that you have either a dead battery or just need a reset. unplug the power cord and then remove the battery. wait two minutes and reinstall the battery.
this will reset everything. now try turning it on. if it won't come on plug in the power cord and charge the battery for 30 minutes before attempting to power up.

hi,Please try following DIY1.Please remove the battery and then press the power button for a minute without connecting the adaptor then refix the battery and check whether it is working.2.Check after removing the battery with adaptor only.3.If then also it is not working check whether the num lock is responding if yes then this is a RAM refixing or changing issue otherwise a motherboard issue if the adaptor is working fine.

i have the same problem...laptop randomly shuts down, but its even done it within a minute of turning it on so i don't think its a heat issue. Sometimes it'll run for over an hour with no problem and never shut down, but other times it randomly shuts down sometimes within a minute, sometimes maybe 10 mins, sometimes 30 mins or more ...its maddening! i'd love to find a solution if anyone's found one. Thanks.
